When you burn a candle it is a chemical reaction (flammability). The candle wax changes from wax into something new that goes into the air. The wax does NOT disappear. This is because the law of conservation of matter states that nothing can be created or destroyed. So matter (the candle wax) is NOT destroyed, just changed into something else.

Do Now Answer:

A homogeneous mixture is when you mix 2 or more things together. You can be 2 types of homogeneous mixtures; a solution or a colloid. A solution is made up of a solute and a solvent. A solvent dissolves the solute. The solute is what is being dissolved. An example is sugar water. Sugar is the solute and water is the solvent. If you are not a solution you are a colloid. A colloid is a mixture of 2 or more substances but you cannot pass light through it. An example of a colloid is milk or soy sauce.
